PUMP.

SPECIFICATION forming part of Letters Patent No. 531,735, dated January 1, l 895.

Application filed September 26,1892. Serial No. 446,914. (No model) To @ZJ whom it :r1/ay concern:

Be it known that I, HANS MoRrsNsnN, a citizen of the United States, residing at Leadville, in the county of Lake and State of Colorado, have invented certain new and useful Improvements in Pumps; and Ido declare the following to he a full, clear, and exact description, of the invention, such as will enable others skilled in the art to which it appertaius to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specication.

My invention relates to pumps.

The object of my invention, more particuylarly stated, is to provide a double-acting balanced hydraulic pump for the purpose of pumping or transferring any liquid within the capabilities of the device.

With this purpose in view my invention consists in the following construction and combination of parts, which will first be fully set forth and described in the specification and the features of novelty then specified in the claim.

Figure l represents a central vertical section of a device to which I have applied my improvements. Fig.2 is a horizontal section along the line rc rc of Fig. 1. Fig. 3 is a horizontal section upon the line y y of Fig. l. Fig. 4 is a detail vertical section hereinafter referred to, and Fig. 5 is another detail section to which further reference will be made.

In the drawings-A represents a valve located at the bottom of my pump device arranged to open inwardly, and close against any outward tlow.

B is a pipe extension leading upwardly from valve A, and terminating in a double leg communicating with the double cylinders C and D. These cylinders are provided with valves E at their lower ends, which open inwardly and close outwardly against the iiow of liquid, and have heads F at their upper ends. Between these double cylinders C and D is an intermediate cylinder or pipe Gr through which liquid is introduced from above for starting the double-acting pump. The lower end of pipe G terminates in a return-bend pipe H leading to the dischargeoutlets I and J. These discharge outlets are controlled by the valves K and L, which are so arranged relatively that when one is opened the other is closed, and vice versa.

M and N are link connections which are rigid respectively with the valves K and L, their free ends projecting toward and alongside each other where they pass through a loop O in the piston-rod P.

Q is a small cylinder securely bolted or otherwise secured to the central cylinder or pipe G, and R is a piston moving therein to which the piston-rod P is attached. Suitable ports are provided for this cylinder Q with pipe-connections leading therefrom to a Fluid pressure supply, so that the piston-arm may be caused to move up or down, carrying with it the loop O on the piston-rod and the links M and N projecting therethrough, whereby, When the piston is at the downward limit of its stroke, it will cause the valve K to open and the valve L to close, and when the piston is at the upper end of the stroke, to reverse the valves. The former position of the valves is shown in Fig. l.

= Leading from the cylinders C. and D. are the discharge pipes or columns S and T, which may terminate at any suitable point. U are cylindrical pieces having Huid passages, diametrically arranged therein, for the atmospheric pressure to send water in hy valve A, pipe B, valves E and E, cylinders C and D through `fluid passages in U into discharge pipes or columns S and T. The pieces V are simply radially slitted sleeves surrounding the pipes S and T.

V is a pipe communicating with the central cylinder or pipe G, and constitutes a pressure column to operate the pump. The height of this pipe is always greater than that of either of the discharge pipes S and T. Communicating with the pipe is an air and water chamber W from which a pipe X in turn leads to some pump connection for a moving power not necessarily shown in the drawing. The pressure or weight of water in pipe V, being greater than the height or weight of water in either of the discharge pipes S or T, it follows that should the valve K he opened, for instance, the water will flow downwardly through pipe V and upwardly through pipe S, with speed according to pressure. When valve K is closed,

the water still moves forward in pipe S, and thereby `it allowsthe atmospheric pressurev to send water through valve A, pipe B, valve E,

the piston in the cylinder' Q the valveLisopen, the water in column V will flow downwardly therein', and upwardly through valve L into the discharge pipe, with speed according to pressure or moving power. Whenthe valve L is closed the water in discharge pipe T still moves forward, and by this allows the atmospheric pressure to send water through valve A, pipe B, valve E, cylinderD, through fluid passages in U, into discharge pipe T as described.

The air chamber XV enables me to add,

when desired to the natural gravity tlow of ay column of. waterthrough pipe V, necessary to operate both the discharge pipes, an air pressure of varying force as moving power to add to the effectiveness of the weight of the pressure column.

A force pump of some approved construction is employed'to continuously force water through the pipe X into and down the pipe V for the purpose of Vcontinuing the operation of my double balanced pump. The weight of the downwardly moving column of waterin pipe V is arranged to be alternately transferred by the valve connections from one to the other of the discharge columns S and T for the purpose ot'k giving an upward momentum to the water in those columns sufficient to cause a more or less complete vacuum in the chambers C and D, whereby water is pumped through the foot-valve A and Vdischarged through the discharge columns.

The cylindrical pieces U may be employed as sleeves upon the lower ends of the pipes S and T, with a view of strengthening the connection; or the sleeves U may be revolu ble about the pipes, with the slots in said sleeves and pipes adapted to adjustahly register for the purpose of controlling the amount of fluid iiowing through the pipes S and T.

I claim- In a pump, the combination ot a vertical inlet pressure column or pipe and two vertical discharge columns or pipes, both having communication at their lower ends with the pressure column, a pump inlet having connection with both. the `discharge columns, valves for controllingcomm unication between each ot' thek discharge columns and the pressure column, mechanism for alternately opening and closing said valves, and means for- :forcing water down the pressure column.

In testimony whereof I affix my sign aturein presence of two witnesses.
